IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent No. 38,942, dated June 23, 1863.

To aZZ whom it may concern..- 1

Be it known that I, N. A. BOYNTON, of the city, county, and State of New York, have invented certain new and useful Improvements in Stoves and Air-Heating Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure lis a side view of nly invention, partly in section 5 Fig. 2, a vertical central section of the same, taken in the line x fr, Fig. 1.

Similar letters of reference indicate corresponding parts in the two gures.

This invention consists in ina-king the magazine-cylinder, tire-chamber, fire-fines, gaschamber, and window projections all in one piece, as hereinafter set forth.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the hre-chamber of the stove or furnace, which lis circular in its horizontal section and of arch or rounded form at its upper part. The body of the iirechamber gradually diminishes in diameter from itsl top toward its bottom, and at the center ofthe upper part of said chamber there is a chamber, B, of cylindrical or approximate form, which serves as a magazine or coal-receptacle. This magazine projects some distance downward within the fire-chamber, as shown clearly in Fig. 2, and on the upper part of the tire'chamber, all around the magazine, there are vertical tubular projections c, to receive vertical pipes which serve as iues. (See both gures.) The hre-chamber A is provided with an inclined tubular projection C, in the outer end of which there is inserted a mica window, D. The tubular projection C has such a relative position with the fire-chamber that the fire may be distinctly seen through it. One projection, G, is only shown in the drawings, but any desired number may be used and they, with the tire-chamber, magazine, vertical projections a, andgaschamber b, are all cast in one piece. The magazine B is supplied with coal at its upper end, the coal passing down into the recharnber and supplying or feeding the latter. Coal, as is well known, when lying in a heap or When passed down through a tube into a chamber below, will spread, so as to form an angle of aboutt'orty-live degrees, as indicated in redin Fig. 2, and the relative position to the tubular projection G with the tire-chamber is such that the coal cannot enter it; hence the mica D cannot be injured in consequence of the coal coming in contact with it.. In consequence of having the magazine extend down some distance into the firechamber a space, b, is allowed all around the top of the fuel in the fire-chamber, directly underneath the vertical projections at, on which the iues are tted. This space b admits of an equal draft all around the fire-chamber, as all the ues communicate with the space b, and a free circulation for lthe products\of combustion is allowed above the fuel all around the upper surface ofthe same. By this means the consumption of the fuel in the tire-chamber is rendered uniform throughout the entire mass.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Making the magazine-cylinder, tire-chamber, fire-fines, gas-chamber, and Window projections all in one piece, as herein shown and described.
